INVALID-BED.

SPECIFICATION forming part of Letters Patent No. 64,158, dated December 1, 1891, Application filed April 30,1891. Serial No. 391,063- (No model.) Patented in Canada January 28, 1891, No. 35,891.

To all whom it may concern.-

Be it known that we, THOMAS E. KAISER and JONATHAN WILKINSON, subjects of the Queen of the United Kingdom of Great Britain and Ireland, residing in the town of Oshawa, in the county and Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in' Adjustable Invalid-Bed Appliances, (for which we have obtained a patent in Canada, No. 35,891, bearing date January 28, 1891,) of which the following is a specification.

Our inventionrelates to an improvement in invalid-beds, its object being to provide means to facilitate the nursing of persons helplessly sick, and to reduce the labor and danger in connection with the moving of sick persons to a minimum.

A further object is to construct'the devices in such a manner that either or both ends or the sides of the bed may be elevated at will.

With these objects in view the invention consistsin the combination, with a bedstead, of a movable bed located thereon, cords for suspending said movable bed, and adjustable clutches with which said cords are connected, whereby either or both ends or either side of the movable bed may be elevated.

The invention also consists in the combination, with a bedstead and a movable bed, of a revoluble axle, adjustable clutches at each end of said axle connected with the movable bed and so constructed and arranged that by manipulating said clutches and rotating the shaft the movable bed may be elevated at either or both ends or either side.

The invention also consists in certain novel features of construction and combinations and arrangement of parts, as hereinafter set forth, and pointed out in the claim.

' In the accompanying drawings, Figure l is a perspective side view of the adjustable invalid-bed appliance embodying the features of our invention. Fig. 2 is a perspective Figs. 3 and 4 are an end view and sectional view, respectively, of the revolving axle forming part of our invention.

In the drawings, A is a frame consisting of two substantial upright wooden posts or 001- umns securely joined together by girts at the top and bottom thereof. To the tops of said posts are affixed the brackets on a.

At the head of the bedstead a substantial wooden cross piece or beam B, which is attached to the posts at the head of the bed by straps or in any other secure manner, is placed, and from the said beam B and the brackets a a is suspended the movable canvas bed 0, by means of the cords, hereinafter more particularly referred to. The beam 13 is provided with buffers of cork or other suit-- able material to prevent abrasion of the bedstead.

In hospital-beds and all bedsteads having low heads a substantial wooden frame similar in construction to the frame A is placed at the head of such bed, and from the brackets attached to said frame thehead of the canvas bed 0 is suspended, the sheave-pulleys 1, attached to the lower part of the posts at the head of said bedstead, as hereinafter described, being attached to the bottom girt of the substituted frame. The canvas bed 0- is a rectangular wooden frame coveredwith strong canvas, having an aperture 2 in the center thereof and provided with four sheave-pulleys 3, one at each corner of said frame. The brackets a a are provided with two hooks 4, one to each bracket, and from each of these hooks is suspended a swivel sheave-pulley 5. There are two sheavepulleys 6 attached to or suspended from the beam B. Atthe bottom of each of the posts at the head of the bedstead is fixed a sheavepulley 1, and upon the bottom girt, which connects the two upright posts of the frame A, are fixed two sheave-pulleys 7.

It will be seen from the foregoing description that there are twelve pulleys employed in the lifting mechanism of the appliance.

In the frame A an iron axle D is placed at a height sufficient to allow the axle to operate free from the foot of the bed, the ends of the axle D revolving in journals bored into the posts of the said frame. The end of the axle D at the outside postof theframe Aprojects through its journal far enough to permit the attachment of the crank 01. The axle D isprovided at its end next to the crank 61' with a ratchet-wheel c, and the pawl 79 ispivoted to one of the upright posts of the frame A, as shown in the drawings, Fig. 2,-so that the canvas bed 0 maybe securely maintained at any desired height. The axle D is also provided with two double iron clutches, one at each end of said axle. Each clutch is composed-of three parts, F F being the stationary parts, which are rigidly secured to axle movable parts E E and G G when it is def sired to, throw. any or all of the said ovable parts in locking engagement, with the axle D.v There are four ropes or cables requ red o. operate the lifting mechanism of the appli. ance, and they are arranged in tw0.pairs, one pair being on each side of the bedOJhe said arrangement being more particularly de scribed as follows, that is to say: Beginning ith the ropes 10 on the side of the: bed next to the crank d, one of the aid opes. 0.1: cords, having been first knotted, is passed through the aperture in the clutch E, as, shown in, the. drawings, (this being done before-E, is placed on the axle D.) The rope is then passed u;p v wardgly through an anti-fricti0n pulley, as; shown in the drawings, Fig. 1, t0. and through the pulley 5, aftta ched to. the bracket a, thence directly downward to and through the pulley 3' at the foot of the canvas bed C, thenceupward to. the bracket or, towhich it is-v securelyattached. The other rope on the same side of the bed that is, the-side'n ext to the cran-k d'-.-. is, having been previously knotted, passed through the aperture in the clutch G, (this also, being done before Gis placed on the axle D.) The rope is then passed directly downwardto. and through one of the pulleys 7, attac-hed to the bottom girt; of the frame. A, thence. underthe bed along the whole length thereof to and through thepulley 1, attached to the bottom part of the post at the corre-. spending side of the head of the bedstead, thence directly upward to and through the pulley 6, attached, to the beam B, thence di-. rectly downward to and through the pulley 3, attached to the head of the canvas. bed 0,

V thence upward to the beam B, to which the rope is then securely attached. The rope-son the other; side of the bed: are placed in similar positions and follow similar courses, respectively.v

' The manner in which the several parts comprising our invention operate is as follows, that is to say: When it is desired to raise the will slide the clutch-jaws I into the recesses in G G, thus throwing the parts G G in lock ing engagement with the axle D. I The parts E E, not being locked with the said axle, will permit the same to revolve freely in E E.

The ropes attached to G G are attached at.

their other ends to. the pulleys at the head of the bed 0. It will'therefore be seenthat, these ropes and 110 others, being acted upon, the head of the bed C only will be raised. To raise. the foot, of the bed 0, the operator will slide the clutch-jaws. 1 into the recesses in E E, thusthrowing the parts E E" in looking engagement, with the axle D,-. The parts be raised;

G G, not being locked with the said axle, will permit the same to revolve freely in G G". The ropes, or cords attached toE: E. are attached at their other ends to the pulleys at the foot. of the bed 0., It will therefore be seen that, these ropes. and no. others being acted upon, the foot of the. bed 0' only will To raise the side of the bed G 1 next to the crank d, the operator-will slide 1 the clutchdaw 1 into the recess in E and the clutch-jaw 1 into. the. recess in G, thus throw-1 fin-g the parts E; G in lockingengagement with the men. The parts E G, not being locked with the said axle, will permit the 5 same to. revolve freely in E G". The ropes 0r cords attached to-EiG are attached'attheir 1 other ends to the pulleys. at the head and 3 foot, respectively, of the. canvas bed Gen the t same side.

These ropefi and no others he,

. ing acted upon, the side, of the canvas bed 0 next to the. crank at only will be raised. To raise the other side of the canvasbed G, the par-ts E G. wi'l1,by the manipulation of the clutch-jawsl I, be thrownin looking engagement with the axleD. The parts 'E. G, not. being locked with axle D, will permit; the same to revolve; freely in. E G. The ropes or cords attached to. the parts E." G are attached at their otherends to the pulleys at the head and foot, respectively, on the same side. These ropes and no others being acted upon, the. side of the canvas bed- Gi to which these ropes are-attached only will be raised. The lower-ingot the bedO is accom plished; in all cases by raising the pawl 70,

thus releasing",- theratchet-wheel e, and thereby allowing the axle D to. revolve in the con-.

trary direction until the lowering is accomplished.

What we claim a'sour invention, and desire to secure by Letters Patent, is-

The combination, with a bedstead, a mov- IIO able bed,"and an adj ustable frame, ofan axle of said movable bed may beelevated, submounted on said frame, adjustable clutches stantially as set forth. I v

carried by said axle, and cords carried by suitable pulleys, said cords being attached to the movable bed and to said clutches, whereby either or both ends of the movable bed may be elevated and whereby either side T. EJKAISER. JON. WILKINSON.
